Vazquez, 49, was warming up his beige 1999 Chevy Tahoe at about 8 p.m. when two men -- one carrying a handgun -- walked up and ordered him out of the SUV, his son told NBC Chicago.

The son, who asked to not be identified, said his father was shot a total of four times; one bullet grazed his head, two others hit him in the left leg and a fourth struck him in the chest. The son said the attackers pulled Vazquez out of the vehicle and stomped on his face before driving off with the Tahoe.

Vazquez underwent surgery Thursday to remove all but one bullet which remains lodged underneath his ribs. His son says he will need one or more surgeries, and that he's talking but unable to eat. He says his dad is a hardworking family man who did not deserve to be attacked.
